"Perfect sump pump installation
and foundation repair. These guys know what they're doing. I had tons of
cracks in the concrete walls and floors of my basement and Dry-X
completely stopped the water from coming in. And they got good sump
pumps for back-up just in case we have another flooding season.

Sump Pump Installation FAQs, answered by experts

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.
